Is it the one where vendors are upstreaming their drivers to Linux mainline, properly supporting them in tree, and users are able to audit and trust their phones for the first time ever?

Everything else is a compromise trying to please vendors who are only trying to exploit users for profit through planned obsolescence and withholding knowledge of how their devices work.
